Retrieve mysql value from php for radio buttons not working - php

I have table address in my database. I put the value=$Id; for my radio button but I have no idea why it's not working. No error shown make me even confuse and I need help since I am still new to php. When I put 2 address and I checked the radio button the address did not change. It only take the latest one that user inserted.
$userid=$_SESSION["userID"];
$sql="SELECT * FROM customer where ID='$userid'";
$result = mysqli_query( $con,$sql);
while($row = mysqli_fetch_array($result))
{
$Id=$row['Id'];
$OrderID=$row['OrderID'];
$ID=$row['ID'];
$Name=$row['Name'];
$Email=$row['Email'];
$Address=$row['Address'];
$PostalCode=$row['PostalCode'];
$City=$row['City'];
$State=$row['State'];
$mobile=$row['mobile_number'];
// $total=$total+$pSubtotal;
// $totalWeight=$totalWeight+$subWeight;
echo "<input type=\"radio\" name=\"select\" value=\"$Id\"> <label>$Name</label><br>";
echo "$Address<br>";
echo "$PostalCode $City<br>";
echo "$State";
echo "<div> </div>";
echo "<img src=\"images/phone-icon.png\" width=\"20\" height=\"20\"> $mobile<br>";
echo "<img src=\"images/email.png\" width=\"20\" height=\"20\"> $Email<br>";
echo "<div> </div>";
echo "<div class=\"col-xs-12 col-lg-12\" style=\"border-bottom:1px solid #ccc;\"></div>";
}
if(isset($_POST["pay"])){
$userid=$_SESSION["userID"];
$final_price=$_POST["final_price"];
$name=$_POST["name"];
$email=$_POST["email"];
$postcode=$_POST["postcode"];
//echo $postcode;
$mobile_number=$_POST["mobile_number"];
//echo $name;
$radio=$_POST['select'];
if(isset($radio)){
$sql="select Id,Name,mobile_number,Email,Address,PostalCode,City,State from customer where Id='$radio'";
echo $sql;
$res = mysqli_query($con,$sql);
if($rows=mysqli_fetch_array($res)){
$idx=$rows['Id'];
$name=$rows['Name'];
$mobile=$rows['mobile_number'];
$email=$rows['Email'];
$address=$rows['Address'];
$postcode=$rows['PostalCode'];
$city=$rows['City'];
$state=$rows['State'];
}
}
}

How are you submiting those information?
You just select the desired radio and press Submit?
Another point is, you do have 2 lines doing the same thing:
$Id=$row['Id'];
$ID=$row['ID'];
You should avoid those kind of thing.
Use the correct uppercase/lowercase according to your database table field name.
Did you use a var_dump($row) to check the correct case ?
That can be the problem.

Sorry if this is not the right answer, I'm not exactly sure what you are asking but I think you mean to use an associative array? Try using mysqli_fetch_assoc.

Get the values of the ticked checkboxes in php

I am currently building a web application. In my application, a load some data from mysql and I display them as a table in my website. Additionally I add another column that consists of different checkboxes. My source code of displaying the table is called by a function that is located in another page. The source code odf the function is the following :
function user_clients_table() {
$con = mysql_connect("localhost","root",'');
if(!$con){
die("Cannot Connect" . mysql_error());
}
mysql_select_db("client_app",$con);
$get_user_clients = "SELECT `ID`,`Name`,`SurName` FROM `clients` ";
$clients = mysql_query($get_user_clients,$con);
echo "<table border=2>
<tr>
<th>ID</th>
<th>Name</th>
<th>SurName</th>
<th>Receive Message</th>
</tr>";
while($record = mysql_fetch_array($clients)){
echo "<form action=pushnotification.php method=post>";
echo "<tr>";
echo "<td>".$record['ID']." </td>";
echo "<td>".$record['Name']." </td>";
echo "<td>".$record['SurName']." </td>";
echo "<td>"."<input type=checkbox name=checkbox[] value=".$record['ID']." />". "</td>";
echo "</tr>";
echo "</form>";
}
echo "</table>";
mysql_close();
}
The function works fine, after i call the function my webpage looks like this:
I want next to display the client number whose check box has been checked after i click the button send. For example if i checked only the first check box and submit it, i want to echo the client id that matches thsi checkbox, in this case i will echo '2'. My approach to this is the following:
if(isset($_POST['send'])){
if(!empty($_POST['checkbox'])) {
// Counting number of checked checkboxes.
$checked_count = count($_POST['checkbox']);
echo "You have selected following ".$checked_count." option(s): <br/>";
// Loop to store and display values of individual checked checkbox.
foreach($_POST['checkbox'] as $selected) {
echo "<p>".$selected ."</p>";
}
echo "<br/><b>Note :</b> <span>Similarily, You Can Also Perform CRUD Operations using These Selected Values.</span>";
}
else{
echo "<b>Please Select Atleast One Option.</b>";
}
}
It works but only for the first checkbox, if I select the other checkboxes without the first one I doesn't display anything.
Can someone please help me?
Thanks in Regards
Each checkbox is in it's own form, so when you are submitting you are submitting the first form (the first checkbox), and that is why you are getting the current action. Put the form tags outside the loop

inserting variables into php echo of a submit button

Hi I'm looking to insert a varible into a submit buttons name when I echo it via a loop so that each button has a unique name
$x=0;
$sql = "SELECT * FROM userstats ORDER BY RAND() LIMIT 5; ";
$result = mysqli_query($link,$sql);
echo ("<table>");
echo ("<tr>");
echo ("<th>Name</th>");
echo ("<th>Level</th>");
echo ("<th>Stats</th>");
echo ("<th>Win Chance</th>");
echo ("<th>Action</th>");
echo ("</tr>");
while($row = mysqli_fetch_assoc($result)){
if($row['username'] !== $_SESSION['username']){//add so it dosent put duplicates
echo("<tr>");
echo("<th>".$row['username']." </th>");
echo("<th>Level: ".$row['Level']." </th>");
echo("<th>Player Stats:".$row['Attack']."/".$row['Defence']." </th>");
echo("<th>Win Chance: ");
echo(CalculateWinChance($link,$row['Defence']));
echo("<input type='hidden' name='".$x."hidden1' value='".$row['Defence']."' />");
echo("<input type='hidden' name='".$x."hidden2' value='".$row['username']."' />");
echo("<th><input type='submit' name = 'Attack_Btn".$x."' onclick = 'BattlePlayers()' value ='Attack'></th>");
echo("</tr>");
$x=$x+1;
}
}
echo ("</table>");
I tried the above code but it does not change the name attribute? What am I doing wrong here?
you can put that as an answer can ill accept it :) – GregHBushnell

php fetch column values from database and display in html table column

I have a table in database name Accounts in which i have many rows and many columns, i want to show a column Account (all values) in my html table. I have tried many method to show a specific column values without using index in html using php and I am using MySql.
$storeArray = Array();
while($rowval = mysql_fetch_array($whole, MYSQL_ASSOC))
{
$storeArray[] = $rowval['Account'];
$status= $rowval['status'];
$ph1= $rowval['Phone1'];
$ph2= $rowval['Phone2'];
}
by using <?php echo $storeArray[0]; ?> and <?php echo $storeArray[1]; ?> in <td> i got the solution. My question is there any way, it automatically show all values without providing any index?
$conn=new mysqli("localhost","root","","your_db");
$rows=$conn->query("select username from User");
echo "<table border='1'>";
echo "<tr><th>Username</th></tr>";
while(list($username)=$rows->fetch_row()){
echo "<tr><td>$username</td></tr>";
}
echo "</table>";
This is a pretty elaborate question. I think the best I can do is point you in the right direction. There is a good tutorial for this on w3schools.com. You should at least read these:
PHP - Connect to MySQL
PHP - Select Data From MySQL
and maybe
PHP - Limit Data Selections From MySQL
**file user.php**
<?php
$conn=new mysqli("localhost","root","","your_db");
$rows=$conn->query("select id,username from User");
echo "<table border='1'>";
echo "<tr><th>Username</th></tr>";
while(list($id,$username)=$rows->fetch_row()){
echo "<tr>";
echo "<td>";
echo "<form action='user_details.php' target='_blank' method='post'>";
echo "<input type='hidden' name='txtId' value='$id' />";
echo "$id - $username";
echo "<input type='submit' name='btnView' value='View' />";
echo "</form>";
echo "</td>";
echo "</tr>";
}
echo "</table>";
?>
**file user_details.php**
<?php
if(isset($_POST["btnView"])){
$id=$_POST["txtId"];
$conn=new mysqli("localhost","root","","your_db");
$row=$conn->query("select id,username,email,phone from User where id='$id'");
list($id,$username,$email,$phone)=$row->fetch_row();
echo $id," ",$username," ",$email," ",$phone;
}
?>
if you want to fetch more than one database column in your html table column.
$conn=new mysqli("localhost","root","","your_db");
$rows=$conn->query("select col1,col2 from Tablename");
echo "<table border='1'>";
echo "<tr><th>col1</th><th>col2</th></tr>";
while(list($col1, $col2)=$rows->fetch_row())
{
echo "<tr><td>$col1</td><td>$col2</tr>";
}
echo "</table>";

MSSQL and PHP: Select specific row based on which button is clicked

I am making a website for a mock book database using MSSQL where users can search for different books and select particular books that they might like to add to a list of favorites under their account name. The problem I am having is that I have no idea how to differentiate which book selection they want to add to their favorites because I can't figure out how to set the ISBN of the book, which uniquely identifies it, to a php session variable. If anyone can shed some light on this I would appreciate it, have been trying to figure it out all day.
//Set up connection
$connection = mssql_connect("$hostName", "$sqlUsername", "$sqlPassword")
or die("ERROR: selecting database server failed.");
//Select database
mssql_select_db($databaseName, $connection)
or die("ERROR: Selecting database failed");
//Search to run if searching for book title
if(isset($_GET['searchBook'])){
$searchBook = $_GET['searchBook'];
$query = "SELECT BOOK.ISBN, Title, Author, Publisher, NumberOfPages, Language, LocationName, ListPrice FROM BOOK, PRICE, LOCATION WHERE Title LIKE '%$searchBook%' AND BOOK.ISBN = PRICE.ISBN AND PRICE.LocationID = LOCATION.LocationID";
}
//Search to run is searching for a book author
if(isset($_GET['searchAuthor'])){
$searchAuthor = $_GET['searchAuthor'];
$query = "SELECT BOOK.ISBN, Title, Author, Genre, Publisher, NumberOfPages, Language, LocationName, ListPrice FROM BOOK, PRICE, LOCATION WHERE Author LIKE '%$searchAuthor%' AND BOOK.ISBN = PRICE.ISBN AND PRICE.LocationID = LOCATION.LocationID";
}
//Store query result
$query_result = mssql_query($query, $connection)
or die( "ERROR: Query is wrong");
//Set up table to display search results
echo "<form action=\"addFavorite.php\" method=\"POST\" name=\"table\">";
echo "<table border=1 align=\"center\">";
echo "<tr>";
// fetch attribute names
while ($filed = mssql_fetch_field($query_result)) {
echo "<th>".$filed->name."</th>";
}
echo "<th>Favorite</th>";
echo "</tr>";
// fetch table records
while ($line = mssql_fetch_row($query_result)) {
echo "<tr>\n";
foreach ($line as $eachline) {
echo "<td> $eachline </td>";
}
echo "<td><input name=\"".$line['index']."\" type=\"submit\" value=\"Add To Favorites\"></td>";
echo "</tr>\n";
}
echo "</table>";
echo "</form>";
Not sure if this is relevant but the following code is my best attempt at getting the value of ISBN that corresponds to the row of the button being clicked, which doesn't exactly work like I had hope.
//Get the ISBN
$data = mssql_fetch_assoc($query_result);
$ISBN = $data['ISBN'];
echo $ISBN;
Here is the code for my addFavorite.php which is where the form action is set to. This is the file that needs to know what user is adding a book as a favorite AND what book they are adding to that list.
//Set up connection
$connection = mssql_connect("$hostName", "$sqlUsername", "$sqlPassword")
or die("ERROR: selecting database server failed.");
//Select database
mssql_select_db($databaseName, $connection)
or die("ERROR: Selecting database failed");
$User = $_SESSION['userID'];
//Set up query
$query = "INSERT INTO FAVORITES VALUES(\"$User\",\"**I NEED A SESSION VARIABLE OR SOMETHING TO GO HERE\")";
//Store query result
$query_result = mssql_query($query, $connection)
//or die( "ERROR: Query is wrong");
Any help would be much appreciated. I know it's alot of information and if there is anything that doesn't make sense or I have forgotten to provide please let me know. Thanks.
EDIT
I have tried using the BUTTON instead of using INPUT but the value of the button is not setting to anything for some reason.
echo "<form action=\"addFavorite.php\" method=\"POST\" name=\"table\">";
echo "<table border=1 align=\"center\">";
echo "<tr>";
// fetch attribute names
while ($filed = mssql_fetch_field($query_result)) {
echo "<th>".$filed->name."</th>";
}
echo "<th>Favorite</th>";
echo "</tr>";
// fetch table records **PROBLEM IN HERE since $line['ISBN'] returns nothing**
while ($line = mssql_fetch_row($query_result)) {
echo "<tr>\n";
foreach ($line as $eachline) {
echo "<td> $eachline </td>";
}
echo "<td><button name=\"FavoriteButton\" type=\"submit\" value=\"".$line['ISBN']."\">Add To Favorites</button></td>";
echo "</tr>\n";
}
echo "</table>";
echo "</form>";
EDIT 2
Finally got it working, thanks to everyone for helping! Partial code that was problematic posted below in working condition.
echo "<form action=\"addFavorite.php\" method=\"POST\" name=\"table\">";
echo "<table border=1 align=\"center\">";
echo "<tr>";
// fetch attribute names
while ($filed = mssql_fetch_field($query_result)) {
echo "<th>".$filed->name."</th>";
}
echo "<th>Favorite</th>";
echo "</tr>";
// fetch table records
while ($line = mssql_fetch_row($query_result)) {
echo "<tr>\n";
foreach ($line as $eachline) {
echo "<td> $eachline </td>";
}
echo "<td><button name=\"FavoriteButton\" type=\"submit\" value=\"".$line[0]."\">Add To Favorites</button></td>";
echo "</tr>\n";
}
echo "</table>";
echo "</form>";
Use a BUTTON-element instead of the INPUT-element. That way, you can use the 'value'-attribute of this element to pass the correct value.
echo "<td><button name=\"$line['index']\" value=\"$line['ISBN']\" type=\"submit\">Add to favorites</button></td>";
Although I would suggest using AJAX instead of the above approach for this: use the onclick event from a button to execute javascript that calls a seperate php-file and passes the correct ISBN-number. This is then added to the database and your original page should be refreshed or part of the page reloaded.

PHP MySQL Dropdown box

I have a dropdown box which is populated through MySQL:
echo "<form>";<br>
echo "Please Select Your Event<br />";
echo "<select>";
$results = mysql_query($query)
or die(mysql_error());
while ($row = mysql_fetch_array($results)) {
echo "<option>";
echo $row['eventname'];
echo "</option>";
}
echo "</select>";
echo "<input type='submit' value='Go'>";
echo "</form>";
How do i make it that if one clicks submit it will display a value from a MySQL db
Thanks for the help
Just change your query like SELECT result FROM somedb WHERE eventname = '".$eventname."'
Then you just do: (remember to check before while has user already requested info)
The value was: <?php print $row["result"]; ?>
Remember to check $_POST["eventname"] with htmlspecialchars before inserting it to query.
1) Give a name to your <select>, i.e. <select name='event'>.
2) Redirect your form to the display page (and set method POST): <form method='POST' action='display.php'>
3) just display the selected value: <?php echo $_POST['event']; ?>
If you want to use the same page, give a name to your submit button and then do this:
<?php
if (isset($_POST['submit']))
echo $_POST['event'];
?>
Hope it helps.
